Propolis (bee glue) is a resinous hive product, collected by bees. It possesses versatile biological activity antibacterial, antiviral, fungicidal, anti­ ulcer, immunostimulating, hypotensive, cytostatic, etc. [1]. The chemical com position of propolis ap­ peared to be very complex at least 156 propolis constituents have been identified so far [2,3]. M ost im portant constituents of propolis ap...

Trypanocidal activity was found in the volatile oil of dried Dracocephalum kotschyi. GC-MS analysis determined that the major constituents of the oil were geranial (35.8%), C10H14O (26.6%), limonene (15.8%) and 1,1-dimethoxy decane (14.5%). In order to isolate the unknown biologically active monoterpene, fractionation of the volatile oil was carried out by silica gel column chromatography. The ...

Background & Aim: Peppermint (Mentha piperita L.) oil is one of the most popular and widely used as an essential oil. The aim of this study was to identify of the chemical components of peppermint cultivated in Isfahan climatic conditions. Experimental: The aerial parts of the plants were collected from a filed in Meymeh, Isfahan province in 2012. The essential oil was extracted by a ...

To identify volatile constituents in Typhonium giganteum Engl., and clarify their effects on proliferation of breast cancer T47D cell lines. Volatile constituents in Typhonium giganteum Engl. are extracted by steam distillation, and determined by GC-MS. 24, 48 and 72 h after treatment of T47D cells with different concentrations of Typhonium giganteum Engl. volatile (DJL-V) constituents, methyl ...

The essential oils from four samples of Teucrium lusitanicum and one sample of Teucrium algarbiensis, grown in Algarve (southern Portugal) were analyzed by gas chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS). Seventy-one volatile compounds were identified. Major compounds of T. algarbiensis oil were alpha-pinene (8.3%), sabinene (7.2%), beta-pinene (10.2%), limonene (11.8%)...

Exhaustive hydro-distillation of the leaves of Piper aduncum and fruits of Piper gibbilimbum (Piperaceae) afforded colorless and pale orange colored oils in 0.35 and 0.30 % yields, respectively. Detailed chemical analysis by GC/MS indicated the volatile constituents of Piper aduncum to be composed of dill apiole (43.3%), beta-caryophyllene (8.2%), piperitione (6.7%) and alpha-humulene (5.1%), w...

The chemical composition of the volatile metabolites of Crithmum maritimum harvested from several geographic localities along the Mediterranean coasts was studied by GC and GC-MSD. The major oil constituents were found to be dillapiole, gamma-terpinene, sabinene, limonene and beta-phellandrene. The Western populations were richer in dillapiole, whereas the Southern collections were characterize...
